Our internal medicine service works carefully with our equine surgeons, radiation oncologists and oncologists to provide care for horses with cancer. We can provide a diagnosis with examination of cells by our onsite cytologists or biopsies read by our own specialist veterinary pathologists. The most common tumors in horses are sarcoids, squamous cell carcinomas, melanomas, or lymphoma. Treatment options for various types of cancer are combinations of surgery, liquid nitrogen freezing, cisplatin beads or carboplatin injections, chemotherapy and radiation therapy. The use of chemotherapy for horses is becoming increasing common and we are currently performing research with the Harrison School of Pharmacy to determine the best doses for horses. The new canine melanoma vaccine is also being used at Auburn University to treat horses with melanomas. It is only available through veterinary oncologists. Auburn University is also one of the world leaders in the use of radiation therapy. There are only 6 institutions that can perform gamma radiation via a linear accelerator on large animals. Auburn was one of the first, and we receive referrals for radiation therapy from all over the country.
